Microsoft has released the final build (4763.1000) of Office 2010 to MSDN and TechNet subscribers today.

Microsoft said on Friday that its new Office suite, due in May for businesses and June for consumers, had reached the released to manufacturing (RTM) milestone. The build leaked shortly after the official RTM announcement last Friday. Volume License customers with Software Assurance will be able to download the RTM bits on April 27

Microsoft is currently running an Office 2010 Technology Guarantee. Neowin revealed Microsoft's plans for the guarantee program. Customers who purchase Office 2007, or a new PC with Office 2007, and activate it between March 5, 2010 and September 30, 2010 will be offered a free upgrade to Office 2010. Copies will be available online, via download, at no additional cost.

Microsoft is holding business launch event for Office 2010 in New York on May 12. Consumers will not be able to purchase the product until June. Although Microsoft officials will not confirm the exact date, Neowin firmly believes this will be June 15. In January Microsoft announced Office 2010 pricing. The professional edition will retail for $499 boxed. Office 2010 will be released in at least five different flavours, including a free version that includes Microsoft Word and Excel, but comes with limited functionality and includes advertisements. The editions of Office 2010 will include Starter, Home and Student, Home and Business, Professional and Professional Academic.
